Abstract
Monitoring a state of a rechargeable battery involves repeatedly obtaining at least one measured value related to the battery during discharge of the battery; repeatedly calculating the state of the battery during discharge of the battery based on a previously calculated state of the battery, the measured value and at least one parameter of the battery; before the state of the battery passes a threshold value, updating the parameter of the battery at a first rate; after the state of the battery passes the threshold value, updating the parameter of the battery at a second rate, faster than the first rate; and correcting the state of the battery in response to each update of the parameter.
